Not sure if this is 100% Pizzagate-related but it reeks of child abuse.

It appears that this person(s) is cleverly publishing videos of little girls in ballerina poses (some of them obviously sexual) and asking for monetary donations.

Here is one of the channels with the same videos with the username 'Snuff54'

Some of these videos have millions of views and the user claims to be interested in the beauty of children (only little girls). Here is their 'about' description on the initial channel I found:

I admire the beauty of children and my goal is to show it in my films. That's why I'm shooting on a cinema camera to create a naturalistic image that will give you an opportunity to feel the vitality and beauty of captured moment. Becoming my patron and supporting the channel, you help me to realize this creative task. Thank you very much.

It appears that this person is based in Russia (their main website ends in .ru in addition to the other channel names being Russian) where I'm guessing child porn laws may be more lax. I am not 100% sure on that.

I have reported 5 of the videos on the initial channel but discovered so so many more similar videos on so many channels. I recommended to YouTube that they ban that channel. Sigh. But at least this is a start. Take care all.
